`To MZ whom? t motyconceric:

Be it known that I, GORDON MERRITT, a citizen of the United States, residing'in Ridge'- wood, in the county of Bergen and State of wheel,respectivel`y, whereby the wheel is roo invention t 3o tatably-su ported in the frame and can be lmounted t v erein by displacement ofthe bear'- `ing portions of the frame.

vide an improved. pulley-Wheel or sheave formed out of sheet metal orV other sheet'material in which bearing Ortions are formed by the indenting ofthe s eet material.

In the drawings accompanying andpformperspective view of awindow broken away and showinglthe application-of a'form of my ereto. Fig.` 2 is-a perspective view, partly sectional, of a portion 'of a sliding door and track with a form of my invention a plied thereto. Fig. Sis a side eleva- -tion o one form of myinvention shown in 4po-.

Figs. 4,5, and 6 are-lon itusition for use. y dinal` sections through modiiiedvforms o device.y Fig. 7 is a transverse section onthe line. :1c indicated in Fig. 3, the" pulleywheel being shown in elevation. Fig 8 shows in perspective the form of pulley-wheelshown in'Fig. 5. Fig. 9 is a-persp'ective view ofthe form offrame shown in 'gures heretofore described; and Figs. l0' to 14 are'transversesectional views of modiiied forms of the frame, the structural element and wheel being indicated in broken lines. f

The device is composed of a frame A, supporting a pulley-wheel B. The frame A is shown as composed ofv two side members 19,

- that are joinedv bya suitable connecting member 20 at one end, andy the Apulley-wheel B is suitably mounted between the side members Another objectv of my invention istopro-l 19 and has bearings therein. The members 19 of the frame are preferably arranged parallel, lor at least their longitudinal elements are disposed inparallelism. In the structural element I provide va seat for thev frame in the form of a slot 27, the width ofthe opening corresponding with that of the frame, whereby the frame may be housed therein, the closedend andthe side walls of the slot constitutin a seat for' the frame. In order to prevent ateral displacement of the frame in this seat, the side members 19 are so formed as to have a retaining engagement with the side walls of the seat. .'In Fig. 7 and also Figs. V10 to 14 I show various'congurations thatmaybe given .totheside members to prevent thev lateral displacement of the device. In the present instance the side members are shown as substantially channel-shaped, be`

longitudinal edges, extending outwardly in opposite directions andiengagingy the oppo- :site sides of the structural elementy adjacent the opening. These flangesl are preferably Jformed convex, as shown. Where the flanged sidev members are of less width than the thick- -ness `of the structural element, the latter may be rabbeted on one side, preferably the inner, as indicated in Fig. 7. In Figs. 12 and 13 the sidemembers 19 are cylindrically curved inv stead of being flat, and the side walls of the Opening are correspondingly formed. With the form .shown in Fig'. 12 the walls of the opening would be concave, while with that vex. In Fi .14 the'side'members are shown as V-shape side walls of the openingv would be of correspending configuration.

,The portion connecting the extremities of in transverse section, and the v ing providedv with flanges 22 on the opposite indicated in- Fig'. 13 these walls'would 'be conthe sidemembers 19 may be ofV anydesired y shape. It is found convenient to curve such part, as shown in Figs. 3 to 6, forming asub- `stan'ti'ally.'U-shaped frame, and'these three members areshown in Figs. 3, 5, and 6 as 'made'integrah In Fig'. 4 is shown another form of frame, in which one-half of the connecti-ng portion 20 is integral with each side member 19, the two portionsV thus constitutin the frame being secured together by suit' abe means. "The flanges 22 ofthe side mem-` bers may becontinued around the curved portion 20, and thus constitute one integral flange.

Any suitable form of a pulley-wheel may be rotatably mounted between the side members 19. In Fig. 4 a solid wheel B is shown, having projections 16 engaging socket portions 17 in the frame.

In Figs. 5 and 8 is shown a pulley-wheel in which t'wo substantially similar portions 14, formed of sheet material, are suitably secured together, as by integral clips 13. Each of the portions 14 has formed integral therewith a pivot or journal portion 15, formed by indenting the material outwardly. These pivots 15 engage suitable conoidal socket portions 17, formed in the side members 19 by indenting them outwardly or in opposite directions. The form shown in Fig. 6 is a somewhat similar arrangement; but the side portions 140 of the pulley have sockets 11 formed by indenting the central portions inwardly toward each other and preferably made conoidal. The frame 190 in the present instance has conoidal pivot portions 18, formed by indenting the sides of the frame inwardly toward each other.

In the form shown in Fig. 4 the wheel B can be placed in its bearings before the side members are secured together at their connecting parts butin the form shown in Figs. 5 and 6, where the frame is formed of one integral piec, it is made yieldable or of resilient material, whereby the side portions can be bent apart to mount the wheel in its pivotbearings, and it will be retained therein by the side members returning to their normal relative positions. It will be further observed that when the frame has been inserted in the opening 27 of the structural element 28 its engagement with the side walls thereof will prevent the side members of the frame springing apart, which would release the pulley-wheel, thus insuring the secure mounting of the pulley-wheel in its bearings.

After the pulley-wheel has been mounted in its bearing in the frame the latter is slipped into the opening 27, the upper ends of the frame being either flush with or below the end of the opening. It will be observed that when so placed the bottom or connecting part of the frame will be seated on the bottom wall of the opening, and also that it is entirely prevented from lateral displacement by reason of the flanges 22 engaging the sides cf the opening, and when the cord is passed around the pulley and the sash and weight connected the pulley is held in its seat by reason of the load direction-that is, the strain on the pulley and frame is directly downward, tending to securely retain it in its seat. With such a structure it is clearly evident that no fastening devices, such as screws or nails of any form, are needed to retain the device in its proper position, nor is it required to strike up or indent any portion of the frame, thereby to secure the device in place.

In Fig. 2 is shown the pulley device hereinbefore set forth, but applied in a reverse position and used to support a sliding door 30. The door has a suitable mortise formedv in its bottom edge, in which the pulley device is inserted, the closed or connecting end being put in first. It will be observed that the pulley device is retained in this socket solely by the action of the load directionthat is, by the Weight of the door-and that no fastening devices of any form are used or needed.

In the several forms of pulley herein set forth it is provided with a groove 12 for the purpose of guiding the cord or chain supporting the sash and weight in the window or which in the case of the sliding door engages the ridge on the track; but it is obvious that the periphery of the wheel may be made of any preferred or desired coniiguration in order to engage and support the flexible member passing over it or the particular form of track which the pulley may engage.

It is obvious that other forms of pulleywheel may be applied to my improved form of frame herein set forth and also that other and various ways of rotatably mounting the pulley-wheel desired to be used in this frame may be employed.

Having thus described my invention, I claim- 1. The combination of a p ulley-wheel, and a frame rotatably supporting the wheel, the frame comprising two side members, and a connecting end member, the side members being provided with retaining means extending throughout their length.

2. The combination of a pulley-wheel, and an integral resilient frame rotatably supporting the wheel, the frame comprising two side members and a connecting end member, the side members being provided with retaining means extending throughout their length.

3. The combination of a pulley-wheel, and a substantially U -shaped frame rotatably supporting the wheel, the frame having flanges extending outwardly from both side edges of the side portions of the frame throughout their length.

4. The combination of a pulley-wheel, and a substantially U-shaped frame rotatably supporting the wheel, the sides of the frame being curved in section in opposite direc tions.

5. The combination of a pulley-wheel, and an integral resilient frame of sheet metal rotatably supporting the wheel, the frame comprising two side members and a connecting IIO end member, the side members being pro- ,provided With indented .projections oppositely` disposed to coperate With said inricY dented portions of the Wheel to vconstitute a .j ournaled sup ort for the Wheel.
